Let's assume the Cub's payroll limit is the luxury tax. and that MLBTR's arb estimates are pretty on point. The Cubs have ~65 million in free space this year (before cutting Rondon or Grimm) ~55 million in space next year ~45-50 million in space in 2020 That's a ton of money to spend. I assume the goal is to get one of Harper/Machado next year, which means 2020 will be tight. For that reason I doubt we shop at the tippy top of the pitching market (Darvish, Jake, Wade), but I don't think fitting an Alex Cobb and a Jake McGee into the picture is that hard. There's a lot of ways I imagine we could use our space this year that don't hurt us down the road. A big one would be to fill at least one of our major holes by acquiring an expensive one year commitment. A trade for someone like Brandon McCarthy or JA Happ for the rotation, or Brad Zeigler to fill one of our bullpen spots. We might also see some moves in the name of creative accounting (the luxury tax is based on AAV and not actual salary). The big one would be deals that buy out KB's arb years or Q or Rizzo's option years. Another, unlikely option would be a Heyward deal where we pay his 2018 salary and also most of his 21-23 salary, but not so much in 19-20. And all this is if we have to stay under the tax. In reality, we probably want to stay under for 2018 and then won't care anymore because of the tv money.
